I have stayed at Evan's 3 times and every single time was everything I expected. My wife and I were traveling through Southeast Asia for around 4 weeks and though we would book with little time in advance, Evan was always kind enough to accommodate us (even the last time that he was having trouble with the plumbing, he gave us many options and made sure we were comfortable and satisfied).
All 3 times we stayed at different rooms, they all had different layouts and included a private bathroom. The bathroom was clean and included soap and toilet paper. The bed had only sheets (which was enough for us given the weather) but Evan offered us a duvet (which we didn't take). The a/c works perfectly as well as the in-room safe. The neighborhood we found eclectic (fun!) with everything we needed a few steps away (restaurants, bars, bakery, 7-11, laundry, etc)
The only negative I'd have to say is that the second time we stayed, the bed/mattress was tough as well as the pillows. Not a big deal since we stayed only a few days that time but I might not have been able to rest properly had we stayed for more than a week.
All and all, I highly recommend Evan's place as I would stay here again in a heartbeat.
